Nerve conduction velocity is affected by various physiological parameters like diameter of nerve fibre, age, sex, height and temperature. Very little is known regarding the role of nerve conduction velocities in determining handedness. Present study was conducted to correlate the role of peripheral nerve conduction velocities in determining handedness.
To correlate the role of peripheral nerve conduction velocities in determining handedness.
The study was performed on 40 right handed healthy M.B.B.S. students in the age group ranging from 18 to 25 yrs, free of neurological signs and symptoms.
The sensory and motor nerve conduction velocities of median and ulnar nerves in right and left hand were measured and compared by using “ NICOLET COMPASS PORTA BOOK II” E.M.G. machine.
The data was analysed and Z test was used to calculate the statistical significance.
There was no significant statistical difference in the sensory and motor nerve conduction velocities of median and ulnar nerves in the left and right arm of an individual. The results were found to be equivocal.
Thus it can be concluded that the conduction velocities of the peripheral nerves do not play any role in handedness. It is determined at cerebral level and moreover training plays an important role.
